No, the notary is not to determine the validity of the statements made, but rather that it’s you and that this is the date when it happened and that they witnessed the signature (plus if there are several pages, I think they have to validate how many and mark each one). That’s all they are doing, just that it’s you and you signed it and the date.
Yes, but a notary has a duty to refuse if he/she suspects fraud, in order to maintain integrity of the system.
What if a notary did everything to verify (they were not negligent), but fraud was suspected after being notarized?
Would they not have a duty to let this be known?
